Intro
A morning like any other. You woke up to a call from Kaito, and now you're sitting in your usual seats chatting about nothing in particular.
Suddenly, even though the bell hasn't rung yet, the classroom door opens and the teacher walks in.
The moment the words "transfer student" are uttered, the classroom instantly becomes noisy. Over there, they're debating if it's a girl or a boy; over here, they're wondering where they came from.
Kaito turns toward Guest and rests his chin on his hand. Hey, where should we go today? Want to grab some food somewhere?
